insures- Specification of Letters Patent. Patented 24, 1914 Application filed February 12, 1912. -Serial No. 677,104.

To all whom it may concern Be it known that I, GEORGE W. ADAMS, of Rochester, in. the county of Monroe and State of New York, have invented certain new and useful Improvements in Spools;

and I do hereby declare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, forming a part of thisspecilicat-ion and to the reference-numerals marked thereon.

My invention relates to improvements in spools, with particular reference to metal spools, especially such as are eit'iployed for winding film in cameras, although susceptible of other uses Well, and it has for its object to provide a novel method of se curing a disk on the spindle of a spool, in a simple and ready manner whereby it is impossible to remove the same without breakthe spool.

To these and other ends the invention consists in oertain improvements and combinations of parts, all as will be hereinafter more fully described, the novel featuresthe several figures indicate the same parts.

The present embodiment shows one applyeation of the invention, 1 designating the body portion of the spindle and 2 the re duced end portions. Shoulders 3 are afforded between the body portion 1 and the reduced end portions :2 of the spindle, said shoulders being adapted to support the disks 4. The reduced end portions 2 have formed thereon the annular grooves'5,-as shown.

The'disks 4 are supported on the shoulders 3, and are held against movement on the end.

portions by means of inwardlydirec ed proections or flanges 6. In order to orm the flange 6 for engagement with the groove 5, 1 seat the disk 4 on the shoulder as shown 1n Fig. 1, and then by means off Ea suitable -machine,ap.ply pressure to the digllt at points surrounding the'reduced end portioiuand substantially in vertical alinement with the sl'ioulder 3, so as to upset the metal, and cause it tb flow into the groove 5, as shown in ig 3. When the article is completed, the disk l has an annular recess or indentation 7 formed by the operation on the disk Vl]10h results in the engagem nt of the pro ection or flange within thleggroove 5.

In Fig; 5, I show a inod ed form of the invention, ivhere, instead of forming a continuous projectionmrflange, I provide a ser 1es of projections 8, adapted to engage the groove 5.

\Vhile I have is to-be understood that I do not limit my self to the precise embodiment set forth, but intend to cover by this aaplication any structure wherein a disk is aliixed to a spindle in the manner hereinafter claimedo I claim as my invention:

1. A spool comprising a spindle having a body portion, and a reduced portion, the reduced portion having an annular groove formed thereon, and a disk positionedaboutthe reduced portion and supported against the body portion. said disk having an in wardly directed flange engaging the aforementioned groove and provided with an annular recess or indentation adjacent to said flange on the side farthest from the body portion.

2. A spool' comprising a spindle having an annular groove thereon, and a disk arranged on the spindle and provided with a plurality of inwardly extending project-ions I described my invention-in its particular application to a film spook. itl

engaging said groove,itlie disk having a engaging said groove, the thickness of. the lurality of recesses or indentations in the projections being lessthan the thickness of ace adjacent to said projections and c0ex-' 10 the disk. 1 61 'h tensive with the latter.
